I've got a low traffic mail server running Debian Woody with backports
for SA and Exim:
Exim: 4.34-7.amwoody.1 0
SA: 3.0.2-1
Perl: 5.6.1
Again, low traffic. I rotate daily, so:
$ wc -l /var/log/exim4/mainlog.1
2467 /var/log/exim4/mainlog.1
I just upgraded a few days ago to 3.0 from 2.6.4. The machine is a P4
with 1/2G RAM.
I'm seeing lots of these in my logs:
kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process spamd
You can see here how I run spamd and how there's one child that is a
bit of a memory hog:
ps -aux | grep spamd
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 16610 0.0 0.1 92440 732 ? S Jan05 0:04 /usr/sbin/spamd

root 10432 0.0 0.0 1332 428 pts/6 R 10:33 0:00 grep spamd
I run spamd via exiscan-acl version of Exim
warn message = X-Spam-Score: $spam_score ($spam_bar)
spam = nobody:true
warn message = X-Spam-Report: $spam_report
spam = nobody:true
deny message = This message scored $spam_score spam points.
spam = nobody:true
condition = ${if >{$spam_score_int}{100}{1}{0}}
I suspect --max-conn-per-child is a good protection. Any
recommendation on what to set it to?
Is this a known issue?
